To @ZZ whom it may concern/.j

Be it known that I,'MOKINLEY BOYLE, a citizen of the United States, anda resident of the city of New York, borough of Manhattan, in the countyand State of New York, have invented a new and Improved Dumping-Oar, ofwhich the following is a full, clear, and exact description.

This invention relates to improvements in dumping-cars of that class inwhich the dumping is from the sides.

In dumping-cars the load isgenerally piled to a considerable heightabove the car-body, and therefore when the opening between the car-licorand the open door or siding at the dumping side is limited practicallyto the height. of the end boards the discharge of material is retardedby the door, and therefore slow.

It is the object of my invention to provide a simple and novel means toswing the door to a plane considerably above the plane of the car-bodyand possibly above the ytop of the load, thus providing a Wide openingthrough which the load may quickly discharge.

I will describe a dumping-car embodying.

my invention and then -point out the novel features in the appendedclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

. inwhich similar characters of reference in' dicate corresponding partsin both the figures. Figure 1 is an end view of a dumping-car embodyingmy invention, showingit in normal position; and Fig. 2 is an end view ofthe car in dumping position'.

The body of the car comprises a iioor 1,

fixed end boards 2, and vertically-swingingV doors or side boards 3. Thebody is mounted to swing on the truck 4, the swinging connection ofcourse being at the center of the body. As the means for swinging thedoor or side board .open upon the dumping of a .car is the same at bothsides, a description of one will answer for both.

Rigidly fixed tothe upper portion of the door 3 at each end is a link 5,the said links being pivoted to bolts 6 on the fixed end boards. Fromthe low'er portion of the door links 7 extend to and are mounted toswing on the pivot-bolt 6 for the link 5. There is a swinging connectionbetween each link 5 and the truck-frame. As here shown, each swingingconnection consists of telescopic members 8 9. On one Vof the members isrigidly secured a loop 10, through which the other member slides. Themember 8 is pivotally connected to the link 5, while the member 9 ispivotally connected toa lug 11 on the truckframe. The body is held inits normal 0r level position by means of chains 12, having hook portions13 for engaging with links 14, attached to the truck. Y

In the operation when it is desired to dump the car the chain connectionat the side opposite the dumping side is 'to be released and the bodytilted. During this tilting movement the swinging connection between thecar-body and the truck at the side opposite the dumping side will beelongated, while the connection at the dumping'side will retain itsnormal length. Therefore as the body is moved downward the door or sideboard at the dumping side will be forced upward Ito a point considerablyabove `the body, as clearly indicated in Fig. 2, thus providing a wideopening for the discharge of material. When the car-body is in normalposition, the ends of the end members 8 of the connections betweeninwardly-extended lugs on the links 5 and the truck vwill engage betweenkeepers 15 on the outer members, thus preventing any swinging movementof the members with relation to each other.

It will be noted that the pivots 6 are located off or laterally of thecenter of the end boards,

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a dumping-car, a tilting body, a door, a linkextended from the upper portion of the door and having pivotalconnection with a fixed portion of the car-body outward of thelongitudinal center-of thecar, a link extended from the lower portion ofthe door and engaging with the pivot of the first-named link, andaswinging connecting-bar between said first-named link and the car-truck.

2. In a 'dumping-car, a tilting body, a door at the side thereof, a linkextended from the upperv portion of the door and having pivotalconnection with the end board of the body laterally of the end-boardcenter, a link extended from the lower portion of the door and engagingwith the pivot of the first-named link, and a swinging telescopicconnection between said first-named link and the eartruck.

3. A dumping-ear eomprisinga tilting body having swinging side doors orboards and fixed end boards, links rigidly connected to the upperportions of the doors or side boards laterally of the end-board centerhaving pivotal connection with the end boards, links having rigid4connection with the lower portion of the doors and having connectionwith the pivots for the first-named links. and telescopic bars pivotallyconnected to the rstnamed links and having pivotal connection with thetruck, whereby the telescopic bars opposite the dumping side will beelongated during the dumping, and the telescopic bars at the dumpingside retain their normal length.

In testimony whereof I have signed my naine to this specification in thepresence of two subscribing witnesses.

MCKINLEY BOYLE.
